Hi All

I know this issue is resolved, but for those who want to know a simple workaround, simply add back the brackets after string format
{code:java}
template_string = "this is some string {var} {{var1}}"
template_string.format(var='test')
template_string.replace("{", "{{").replace("}", "}}"){code}

```

s.replace("\{", "{{").replace("}", "}}")

>            Priority: Major

> Found that when {{.format}} is used in a templatable field, it produces weird results. For example:
> {code:none}
> t3 = BashOperator(
>     task_id='wget',
>     bash_command="wget {0}/{{ ds }}".format('google.com'),
>     dag=dag)
> {code}
> produces following result:
> {code:none}
> {bash_operator.py:79} INFO - Running command: wget google.com/{ ds }
> {code}
> But if we change {{bash_command}} to following, it works as expected:
> {code:none}
> bash_command="wget %s/{{ ds }}"%('google.com')
> {code}
> {code:none}
> {bash_operator.py:79} INFO - Running command: wget google.com/2016-08-05
> {code}
